Slumber

Dr. Alice Arnolds studies sleepwalking, night terrors, and sleep paralysis as a sleep doctor. Alice meets the Morgan family after Daniel sees a dark figure and struggles to breathe while sleeping. Daniel’s parents and sister also behave strangely during sleep, and the danger grows after the family enters Alice’s sleep clinic. Alice’s brother died during a frightening sleepwalking event when she was young, so Daniel’s case brings back her old fear. The film uses a cold clinic, dark rooms, loud scares, and a demon story about the Night Hag.

Alice first trusts science, but the attacks lead her to consider old stories about a demon that feeds on sleeping people. The family’s sadness, fear, and guilt shape the nightmares. Alice leads the effort to enter Daniel’s nightmare and faces the memory of her brother while trying to save the boy. The film gives Alice a brave and capable role as the main doctor and rescuer. Her identity is not treated as a political issue, and the story does not focus on modern identity politics, social campaigns, or cultural criticism. The main themes remain sleep, grief, guilt, fear, family danger, and old legends.
